HAR'ROW.

SPECIFICATION forming part of Letters Patent No. 527,973, dated October23, 1894.-

Application filed May 24, 1893- To all whom it may concern.-

Be it known that I, PETER J. HELLER, a citizen of the United States,residing at Montclair, in the county of Essex and State of NewJersey,have invented certain new and useful Improvements in Harrows; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit ap pertains to make and use the same, reference being had to theaccompanying drawings, and

to letters of reference marked thereon, which form a part of thisspecification.

The object of this invention is to increase the efficiency of a harrow,to overcome certain objections heretofore existing and to secure otheradvantages hereinafter referred to.

The invention consists in the improved harof the harrow; Fig. 4, adetail, in elevation, en-.

larged of one of the teeth and the parts connected therewith, and Fig.5, is a section taken through line a: of the same. Fig. 6, represents amodified form of tooth.

In said drawings A, B, (J, D, designate the beams which carry the teeth,and E, the said teeth.

F, G, designate two plates which, together, form a clamp in which theteeth are securely adjusted; said plates being secured to the severalbeams, as indicated in Figs. 1, 2, 3, 4; and 5.

The several beams of the harrow are secured at the front end by a bar,a, and braces b, the two outside beams being pivotally secured, as at a,to permit a slight movement of said beams thereon. At, or near the rearend, the beams are provided with braces c and d which are pivotallysecured to the outer beams and attached to the inner or central beams soas to permit of a lateral adjustment Serial No. 475,352- (No model.)

of the harrow and thus to increase or diminish its width, as will beunderstood upon reference to Fig. 2.

The seat or chair, 9, is supported by means of rodsfif, which are hingedor pivotally secured to the harrow, at, g, and to said seat, at, h, andwork freely in the latter so as to permit the lateral adjustment of theharrow, above referred to, as will be understood upon reference toFigs. 1. 2 and 3.

The seat-bar or rail, H, is adjustable, in the draw-head, H, at thefront or forward end at 1', Fig. 1, to permit a slight adjustment of theseat, as may be desired.

The teeth, E, are preferably made sharp at the front edges and are setso as to incline toward the rear end of the harrow, as will beunderstood upon reference to Figs. 1 and 4; i

the purpose of which is to render the harrow more efiicient in breakingand granulating the soil and to enable it to pass more easily over anobstruction than it would were the teeth blunt and straight, as will beobvious. These objects or results will be further promoted by the curvedform of the teeth, as shown in Fig. 1, or by serrating their edges, asshown in Fig. 6. The shanks or roots of the teeth are provided withmeans, (a series of apertures, j, in the present case) whereby saidteeth may be lowered or lengthened, as they wear off at the points byusage, as will be understood. The clamps F, G, in which the teeth areadjusted, are provided with a holding lug or pin, 70, Fig. 5, which, inthe present case, is formed upon and integral with one side of theclamp. This however is not essential as a separate pin or bolt may befective form of device for the teeth and prevents the teeth from bearingagainst the sides of the beams and wearing them and thereby getting outof proper alignment.

Having thus described my invention, what I claim, and wish to secure byLetters Patent of the United States, is- I 1. Aharrow, consisting ofaframe comprising a rigid T-shaped portion, a series of rear- Wardlyextending bars pivoted to the head of said rigid portion, bracespivotally attached to said bars and having sliding connections with thefoot of the rigid portion, whereby each series may be adjusted laterallyrelative to the rigid portion independently of each other, and angleirons having oppositely extending horizontal extremities secured to saidbraces and forming a support for a seat slidably arranged thereon,substantially as set forth.

2. A harrow consisting of a frame comprising a rigid T-shaped portion, aseries of rear- Wardly extending bars pivoted to the head of said rigidportion, braces pivotally attached to said bars and having slidingconnections with the foot of the rigid portion ,-whereby each series maybe independently and laterally adjusted relative to the rigid portion,angle irons having oppositely extending horizontal extremities, securedto said braces and forming a support for a seat slidably arrangedthereon, an angular draw iron at the head of the frame, a seat barextending from the seat to said draw iron and vertically adjustabletherein, and cutter knives secured to the several bars and the rigidportion of the frame.

3. A harrow consisting of a central beam, and side beams, a seat supportpivotally secured to each series of side beams, the upper ends of whichare adapted to pass each other in substantially parallel directions, aseat pivotally and movably secured upon said passing ends, and a bracesecured to said seat at one end and adjustably secured to the harrow atthe other end, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this13th day of May, 1893.

PETER J. HELLER.
